yTo allfwlwm it may concern:

Beit known that 'I, ERNEST VICTOR STONE, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and. State ofCalifornia, have invented new and useful Improvements in Apparatus for Distilling Mineral Oil, of which the following is a specification.

l -y invention relates to an apparatus for distilling mineral oils. Considerable difficulty has been experienced in distilling heavy mineral oilhaving an asphaltic base and containing little or no hydrocarbons of a low boiling point such as gasolene, for the reason that the carbon resl- "due, would in a short time clog up the rev provided with means for pulverizing the carbon as it is formed and removingthe same from the retort, the process being continuous.

lVith this and otherv objects in view, which will appear as the description proceeds, my invention consists in the construction, combination and arrangement of parts constituting my apparatus hereinafter described and claimed.

In the accompanying drawings, which form a part of this specification, I have shown, by. way of an example, an apparatus suitable for carrying on my process and 1n which,

Figure 1 is a longitudinal vertical section of my apparatus, some parts being shown in elevation for clearness of illustration.

Fig, 2 is a cross section taken on line l 2-2 of Fig. 3.

able means 11 driven by a source of power Fig. 3 is a cross section taken on line 3-3 of Figs. 1 and 2.

Referring to the drawings -10 indicates a cylindrical iron retort provided'with suitnot shown for rotating the same. The retort is slightly inclined from the horizontal. 12 are suitable roller bearings in front and at the rear of the cylinder. 13l is the head of the oil supply end of the cylinder through which by means of an inletlpipe 14 mounted in suitable bearings 15 0n a support 16, the

' oil is supplied to the retort. 17 is a pipe leading to the source of mineral oil in communication with the inlet pipe 14. The retort 10 is heated by means vof a. furnace 1S havlng side walls 19 which extend upwardly in close proximity to the retort and spaced' from theends thereof; 20 designates an oil burner located within the furnace. 21 the head of the delivery end of the retort 10, the latter having a cylindrical extension y10', furnishing a bearing face forthe rear roller bearlng 1 2.L 22 is a vapor outlet pipe passlng through the head 21 and Iwhich is mounted in a suitable bearing 23 or a support 24. 25 is a vapor pipe connecting the vapor outlet pipe 22 and leads to a suitable condensing apparatus, not shown.v

Disposed wlthln they retort 10 is a number of loose iron rods 26 extending approXi-.

mately throughout the length of the retort chamber which serve to crush and grind the carbon formed therein which owing to the slight inclination of the retort will gradu ally pass to the vapor outlet end and fall through apertures 2T disposed in a circle in the wall of the retort 10. A pipe 28 is disposed immediately beneath the retort at the place where the carbon delivery openings 27 lare disposed for the reception of the carbon. Suitable mechanism such as a scroll conveyer 29 removes thc carbon from the bottom of the pipe 28.

It is difiicult to make an air tight joint closing the apertures 27 during the rotation central ring 32 lof a width slightly larger than the diameter of the circularapertures 27' and so disposed that during the rotation of the retort 10, vopposite edges of the ring 32 overlap slightly the apertures 27. On opposite sides of the central ring 32 are flanges 33 extending to the outer face of the retort 10 and forming with the central ring 32 a pair of annular chambers 34 which are in communication with an annularcentral steam chamber 35 by means of openings 36 extending at intervals through the lateral walls of the steam chamber 35. The central steam chamber 35 is in communication by means of pipe 37 with a suitable supply of steam, not shown. It is the object of sup-l plying steam to the annular channels 34 in the ring shaped member 30 so that in place of air steam will enterthe retort through ,the joint formed by the central ring member 32 throughthe apertures 27 into the retort.

vapors andlgases being' taken olf through outlet pipes 22 and 25, the distillation and j cracking being preferably carried out under 20 sub atmospherlc pressure. VArs the retort 10 is rotated the loose ironV rods 26 will v'crush land grind the carbon residue which latter' will gradually, due to the inclination of the retort, movettoward the delivery end of the retort and pass through aperature 27 into the carbon pipe'2-8 from the bottom of v Whichfit is removed to -a lsuitable place by means of the scroll conveyer 29. The quantity of the mineral oil supplied to the retort must be controlled so that the carbon, as it reaches the delivery end of the retort, will be suiiciently dried to be ground to a powder.` The iron rods 26 serve the double purpose of keeping the retort wallsree of carbon and at the same time grinding the carbon to a powder so that the same may be v readily passed'. through the "aperture 2,7'.

The joint 30 providing a chamber of steam about the aperture 27, prevents any access of airv to the interior ofthe retort.

Various ch'anges in construction, arrangement and combination of parts of the apparatus may 'be made by those skilled in the artwithout departing invention as claimed.

1. An vapparatus for distilling mineral oils comprising a cylindrical retort slightly inclined lengthwise and rotatably mounted, a pipe for discharging oil into one end of the retort, a second pipe for leading gas from from the spiritof my j the opposite end of the retort, a furnace fqr heating the retort, iron rods loosely mounted in the retort so that the rotation ofthe retort and the tumbling of the rods Will grind up the carbon, and means for discharging the carbon from the retort.

2. An apparatusl for distilling mineraloils comprising a cylindrical retort 1 rotatably mounted and slightly inclined,'rods mounted in the lretort to tumble as the retort is rotated, a pipe connected to the upper end of the retort for discharging oil into the retort,a second pipe connected to the lower end ofthe" retort for discharging gas, there being radial outlets through the wall of the retortat the lower end,v a ring-shaped member around the retort covering the radial outlets, and a pipe leading from the ring- -shaped member and adapted to register suecessively with the radial outlets to carry away the carbon.

` 3. An apparatus for distilling mineral oils, i

comprising a retort rotatably mounted, a pipe for supplying oil thereto, a second pipe .for leading gases and vapors therefrom,

means for heating the retort, iron rods extending substantiallythroughout the lengthof the retortvloosely mounted in the retort .so that the rotation of theretort and the tumbling of the iron rods will pulverize the carbon, and means for discharging the carbonfrom the retort. l

In testimony whereof I have. signed my name to this s eciication.
